My son & I installed an ARB Bullbar on the 2010 5.7 litre overland Last weekend.
The bar is intende for install on the '05 to 07' WK, so I had to take 1" (about 25mm) around the grill section, then clean & spray the edge before finally , installing the bar.

Tanks for the encouragement fellow GCers . This is just the beginning, I would like to do much more to my car in the coming months. I am investigating lots of other possibilities as far as modifications & additions to what is already a very nice drive.
